'is clear, that is, ice which is free from cloudiness, milkiness or the like, occasioned by air or other substance held entrained.

By my invention l agitate the water to be frozen by drawing from the vessel containing the same and re-injecting into it a part 01 the water to be frozen. This 1 accomplish by means of the system or apparatusg hereinafter described, which I believe to be novel in that I employ as the water agitating means a pulsouieter comprising a piston which is free, that not connected to any external operating means, and which is hydraulically operated by a pump like device, the

space on one side of the piston communicating with said pump like device While the space on the other side is connected with the mass of "water to be frozen. By this means a pluraliq' of masses of water to be Frozen may be simultaneously agitated by aphirality of pulsometers without any path of couinuuiication from one mass of water to another; and by this arrangement, where a tree piston is introduced in a reciprocating column ol' liquid or water there is no leakage through the jiulsoi'ueter from the mass oi water to be frozen, because of the pres ence of water or liquid at all times on both sides of the piston. find it is a part of my invention to provide a system for operating the pulsometcis wherein variations from equality between the volume of the motive liquid pumped and the volume swept through by the pulsometcr pistons are compensated for or automatically taken careof; and wherein air or other gas entrained in or carried by the motive liquid is extracted from or allowed to escape from the motive liquid: and wherein the head under which to be "frozen. From the pulsometers may be made such as to be equal to, greater than or less than the suction head operative when operates toeject the water the pulsometers draw in the water be frozen. I

My invention resides in the features above referred to and in other features o con struction and combination hereinafter described and claimed. For an illustration of one of the forms my invent-ion may take reference is to be had to the accompanying drawings, in whicl Figure 1 is a general View, some parts in elevation and some in section, and some'in perspective, illustrating a form my apparatus or system may take. Fig. 2 is a vertical sectional View through a can contain ing Water part of which has been frozen tgether with a sectional view of a pulsometer and its connections. Fig. 3 is a .lrmgitudina l sectional view, on larger scale, through one form of pulsometer which may be used. Fig. -l is a fragmentary longitudinal sectional View through a pulsometer cylinder, showing therein a modified i'orm oi ice or floating piston.

Referring to thedrawings, l) is pum in; device comprising the piston or plunger l mounted upon the piston rod and mov able thereby within the cylinder in which is motive fluid or liquid i, such as water, oil or other iicahle medium. The piston rod 2 is actuated by the connecting rod connected to the wheel or crank (i which is driven by any suitable means, such, for er;- auiple, as a pinion T driven by the wheel 8 which is driven by the belt 9 from any suitable source of power as a steam engine, electric motor or other suitable device. Communicating; with the interior of the cylinder 2% at its bottom is the pipe ll) which communicates with the pipe or header 11 with which coinn'i'unicate the manifolds or pipes 12 with which communicate the pipes 18 communicating with the interior pulsou'ieters 1 The pulsometer cylinders of the l 14 are provided with the cylinder heads 15. 7

Each pipe13 communicates with a puisometer cylinder 14 through one of its heads .5 while its other head 15 connects with the nozzle 16 projecting to suitable extent into the raw, distilled or other water W, to be 'l ro/on, and disposed in the cans or tanks 11.

Within each pulsometer cylinder i4 is a free piston 1.8. ln the form here illustrated, way of example, this piston 18 has two heads or pistons proper 1%., 19 disposed av dis- 'taucc from each other in order that the pis- .1 mad ton. shall move within the cylinder 1 1 with out binding or cramping. Each of the piston heads 19 is provided with the leather or other washer or gasket 20'for securing a tight running fit with the interior walls of the cylinder. These members 20 are held against the member 19 by the washers 21 I drawn toward each other by the bolt 22 on which are engaged the threaded nut 23 and the lock nut 24. These washers 21 may be of any suitable material, either metaiic, leather or otherwise, whereby at the en of each stroke of the free piston the washer 2.1 will snugly engage and tightly close the aperture within the annular rib or flange or valve seat 24 surrounding the connection to the pipe '13 and nozzle 16. As indicated the pulsometers are preferably disposed above or near the top of the cans 17.

From the pipe or header 11, which may preferably incline downwardly from its conneetion with the pipe 10, extend the pipes 2:3 and 26. (of which 25 may be omitted when head 11 is so inclined) in communication with the pipe 27 which is prefei'ably inclined upwardly, as shown in Fig. 1, terminating at 28 in a part 29 extending upwardly and open to the air and the part 30 extending downwardly and open to the air and communicating with the interior of a pipe 31 which leads to the tank 32. Or the pipe 31 may be omitted entirely; or the pipe 30 may itselfextend down to the tank 32 to deliver into it motive fluid under conditions hereinafter named.

In the pipe 25 is a-check valve 33 which is adapted to open upwardly only, that is, in a direction to allow flow upwardly through pipe 25. Andin pipe 26 is a similar check valve 3 1 allowing flow through it upwardly only through pipe 26.

Communicating with the tank 32 is a pipe connecting with the pipe 10 at or near one of the lower levels of the piping system for the motive fluid. In the pipe 35 is disposed a check valve 36 which allows passage through it in one direction only motive fluid -ito the pipe 10.

Communicating with the piping system for the motive fluid at any suitable point, preferably at or near one of its higher levels, as leader 11, is a pipe 37 communicating with the interior of the air cushion chamber 38 which is closed to the atmosphere and of suitable volume for absorbing shocks in the together by a bolt or other suitable means or the bolt 12 may be omitted and the members 40 and 41 made integral with each other. provided with a. central boss or raised portion &3 adapted to engage and snugly close the valve seats 21 to prevent all possibility of leakage, as hereinbefore described.

The operation of the apparatus or system is as follows: The plunger or piston 1 is moved upwardly and downwardly in successive cycles within the cylinder 3 by any suitable means, for example such as de scribed. In the down stroke the motive fluid 4 is pushed out of the cylinder 3 through the pipe 10 to the header or pipe 11 thence through the manifolds 12 and the connections 13 to one side of the piston 18 in each of the pulsometers. This, as viewed in Fig. 2, causes the free or heating piston 18 to move toward the left and forces out ahead of it through the nozzle 16 a portion of the water to be frozen. This water is ejected with considerable force and causes a circuseries of arrows, Fig. 2. The pulsometer pistons preferably travel until the end of Each of the members 40 and 41 is the cylinder is reached when a plate or washer 21 engages the annular Valve seat 24 and closes communication between the interior of the cylinder 14 and the nozzle 16, thus preventing passage of any motive liquid 4 into the water W should there be any leakage around piston 18. At or near this time, the plunger or piston 1 in the cylinder 3 starts onits return or upward movement and draws up into the cylinder 3 the motive fluid 1 causing a suction on the right hand-side of the piston 18, Fig. 2, and the atmospheric pressure exerted on the top surface of the water in can 17 forces a portion of the water up from the nozzle 16 into the cylinder 11 to theleft of the piston 18. As the upward movement of the plunger. 1 continues the piston 18 of each pulsometer moves toward the right preferably until the right hand washer 21 engages and closes the annular valve 24, thus preventing any water W escaping into the liquid 1, should there be any leakage around piston 18. At or near this time the plunger 1 again starts descending and the piston :18 of each pulsometer moves toward the left ejecting the water into the can. This cycle of operations is continued throughout the freezing of the water W, which, due to the agitation produced, freezes as clear and crystal ice without the formation of milky or cloudy portions.

If the volume swept through-by the piston 1 is less than the sum of the volumes swept through by the pulsometer pistons 18 the pulsometer pistons 18 may not travel the entire length of their cylinders. If the .volumes referred to are equalhowever the entire length o1? their cylinders; anal the same is true if the volume swept through by the ,piston l is larger than the piston di age or other causes to take the piece of any i an: which Wlll also escape through the valves 33 34 or both of them, into the pipe :27 smi to the outer air through pipes 29 or 30,. A

And. in the chamber 38 is maintainea mass of air which, under compression, acts as a cushion or shock absorber forthe shocks which would otherwise be delivereti to the eiping system by the motive fluid 4,
